I heard that church is a big thing in Midwest. On this map, you can see how many different churches are in a small neighborhood of Manhattan, where the space is so expensive. It looks like every trader has his own God.

This is a Scientology Church.

In US, the church is exempt to pay property tax (3%). There are about 50.000 members, who have to pay a lot in order to get in higher ranks. Tom Cruise is an exception, because is one of the most important figures, he just takes the benefits. The church is so strong, that the tax service, gave up after several trials.

 In NY, one of capitals of jazz, I met 3 good musicians who told me that a good part of their revenue comes from concerts at churches. Because there are some many rites, there is a concurrence among them, and they try to attract the public.
